Guinness, for example, stores its yeast strain in liquid nitrogen vapour – at an undisclosed location.

Gearoid Cahill, a Guinness brewer, says that the firm takes many things into account to make the beer taste consistent. The water used in the production for Guinness is tested for levels of calcium as too much or too little can inhibit the enzymes that turn the malt’s starch into sugars. (Malt is simply cereal grain, which is germinated in water but stopped from further germination by being dried in hot air. The sugars that come out of the malt are what the yeast is able to turn into alcohol, among other substances, during fermentation.)
